Howdy y'all. First post.

As the title indicates I have a question about installing the TH8320 thermostat from Honeywell. A little background info first:

My A/C-Heating system is an A/C heatpump system from Ruud/Rheem. For the heat it is single stage electric. It also has an electric coil that provides for emergency heat.

My previous thermostat is an older model Honeywell digital/programmable thermostat. That thermostat is a CT3611R4443 model. It was hooked up as follows:

B < blue wire
C < brown wire
R < red wire
Y/W1 < yellow wire * Y and W1 are jumpered together
G < green wire
W2 < white wire
L < no connection
E < no connection
O < no connection

For the new VisionPRO thermostat this is how I think it needs to be connected:

O/B < blue wire
C < brown wire
R < red wire * R and RC should be jumpered together
Y < yellow wire
G < green wire
AUX < white wire * AUX and E should be jumpered together

Is this the correct wiring? Also, for program setting 0190 for the heat/cool valve should the setting be 0 or 1?

Many thanks in advance.

 

ADDITIONAL INFO:

My outside unit is a 3 1/2 ton Ruud with model number RPKA043JA2. The inside air handler unit is also Ruud with model number UHQA-1608BNV. There are 6 total wires as previously specified going to the thermostat.

 

Your wiring is correct, and option 190 = 1.

 

Thank you Houston204 for your reply. I was curious as to where in my heatpump manual would I find the information that would have told me that option 190 should be set to 1?

Is there a certain section in the manual or a spec in there to look at? Just curious. Maybe you just knew what the setting should be based on your past experience with Ruud heatpumps.

Thanks again.

 

The O/B terminal controls your reversing valve.
O = energized for cooling.
B = energized for heating.
You posted that you were not using the O terminal, so configure the O/B terminal to be B (energized for heating.)

(I also knew that Rheem and Ruud energize the reversing valve to heat.)

 

Ahhhh, I get it. I didn't understand this little tidbit until you posted that little jewel of info. Thanks again!
